Glava glasbruk : En undersökning av föroreningar i mark- och vatten samt ansvaret för dessa enligt miljöbalken

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

Kompostering i kommunal regi: en fallstudie i Arvika Parkf?rvaltning

Arvika Fastighets AB is a municipal subsidiary tasked with managing all green areas in the municipality, with a strong focus on the City Park and plant beds in the city centre. These areas generate large amounts of green waste, which is currently transported to the municipality's composting area at Lycke. Currently, the material is piled up and turned once a year without using the resulting soil for flowerbeds, lawns, and shrub/tree plantings. The purpose of the study is to determine if Arvika can compost the green waste in a more efficient manner and produce weed-free soil ready to be mixed into various substrates for different purposes. Interviews with the Swedish Church and several municipalities in Sweden have been conducted to learn from their experiences and knowledge of how they make their composting work.

Reproduktionens inverkan på det slutliga tryckresultatet med djuptryck på MF-papper

To get an optimal print result with rotogravure on improved newsprint, MF-paper, knowledge aboutwhat adjustment that should be done through the whole production is needed. This degree project investigatesthe reproduction?s effect on the final print result.A test print is done at Quebecor World Nordic Interprint´s regular print unit. The evaluation of theprint shows how important the use of a unit adjusted ICC-profile is for the print quality. A comparisonbetween the two separation methods GCR and UCR shows that Interprint´s present ICC-profile, usingUCR as separation method, gives less missing dots.

?Ge mig ett tält med bubbelpool och jacuzzi, då säger jag ja till friluftsliv? : en komparativ studie om friluftsundervisning

AimOur aim with this study was to examine how outdoor education is designed and experienced in three upper (senior) levels of compulsory school in Stockholm, and to compare it with the Norwegian equivalence.MethodOur method has been interviews with ten teachers, of whom six are Swedish teachers and four are Norwegian teachers. Two Swedish teachers are teaching in other subjects than Physical Education, four are teachers in Physical Education, two are teachers in Norway in Physical Education at and two are teachers in Norway at university level. Questionnaires were used to examine the Swedish pupils? attitudes towards outdoor education. 90 questionnaires were delivered, and 70 answered them.

Variationer av klor, svavel och aska i havrekärna : odlingsfaktorernas inverkan på havrens bränsleegenskaper

The increasing oil prices during the last years have made it profitable to use cereal grains as a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for oat grain grown under different conditions. Oats was chosen because in Sweden it's considered as the cereal with the best fuel qualities.

Eld som naturvårdare : Kärlväxtflora och vegetationsutveckling efter naturvårdsbränning i två småländska naturreservat

This study has taken place in two nature reserves in the municipality of Uppvidinge in the Kronoberg region in southern Sweden. These have been chosen by the County Administrative Board to be part of a bigger landscape of fire affected nature, and prescribed fire has been implemented in these. The areas are called Ösjöbol and Berga fly and have been burned 2012 and 2013 respectively. Non-burned areas have been inventoried as well. Vascular plants and mineral soil have been inventoried with the Hult-Sernander-Du Rietz scale of five levels. Issues emanate from the County Administrative Board?s goals for prescribed fire: how sticks and herbs were affected, how much soil was uncovered, how the structure and fire favoured species were affected, and how deciduous trees and spruces (Picea abies) were affected. The study shows that the soil increased, as well as the fire favoured species.

Tillförsel av använda fosforfilter påverkar inte tillväxten eller fosforupptaget hos korn

The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.

Utvärdering av näringsstatus inför återskapande av kalkkärr vid Hagebyhöga, Östergötland

Calcareous fens constitute a specific habitat which is uncommon in Europe and protected by the EU habitat directive due to its importance to several threatened species. Hagebyhöga in Östergötland is a calcareous fen habitat included in the Natura 2000 Networking Programme. Adjacent to the existing fen, a degraded fen area is situated. The area has been used for agriculture for several years but is now going to be restored to its former state by the county administrative board of Östergötland.When working with restoration of degraded fen areas it is important to aquire knowledge about the chemical soil conditions. Plant growth limited by phosphorus and low fertility are characteristic conditions for calcareous fens, whilst arable land usually is highly fertile and limited by nitrogen.The purpose of this study is to bring forth useful knowledge for restoring the degraded calcareous fen of Hagebyhöga.

Provtagning av trädkärnor för att bedöma föroreningsgraden av klorerade lösningsmedel i grundvatten

Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.

Är reducerad jordbearbetning ett alternativ? :

Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage. In this paper we have tried to find out if reduced tillage is an alternative for farmers.

Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder

This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.

Körskador i gallring : en studie av 21 drabbade objekt i södra Sverige

To guarantee the customers a job satisfactory executed Sydved has been certified by the ISO 14001 standard. One part of the certification is the standards of soil damages. The soil damages were over represented during 1999 and 2000. It was therefore a need to study the problem in order to see what could be done to reduces these damages. A filed study was carried out on 21 subjectively selected stands from the following five districts: Vänersborg, Falköping, Borås, Jönköping and Åseda. As the study is a descriptive study of the soil damages, their character and extension, only stands were tracks were reported were considered.

Att kommunicera miljö ?Sällan ett papper på väggen? : En undersökning om kommunikationsstrategier vid implementering av miljömål i två högstadieskolor

AbstractHeadline To communicate the environment, ?Rarely a paper on the wall?, a study about communication strategies when it comes to internalize a policy in two secondary schools.Number of pages 42 (61 including enclosures)Author Fanny PerssonTutor Peder Hård af SegerstadCourse Media and communication CPeriod Autumn 2007/spring 2008University Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim The purpose of this work was to see what channels of communication are to prefer when working with secondary school pupils, more concrete when speaking about the environment, about the profile of the school and democracy among the pupils.Material/method I am going to visit two secondary schools in the middle of Sweden, one that has an environment certification, and the other one is a regular secondary school. To answer these questions I am going to interview totally four teachers, two from each school, and 12 pupils from each school divided into two groups per school.Main results One of the main results was that the pupils prefer to mix the tutoring for a better way to learn. Another result was that they see their teachers as paragons and that it is more important what the teachers do than what they say.Keywords Environment, Communication, Environment Certifikation, Secondary school, Karl Weick, Communication theory, Understanding, Internalize, Identification, Profile.

Betydelsen av kolkälla och mikrobiell fysiologisk status för temperaturresponsen (Q10) vid nedbrytning av organiskt material :

The increasing threat of climate change has led to a increased need for models to predict future climat. In these models the changes in the soil carbon pools due to changes in microbiel degradation of the organic matter can lead to both positive and negative feedback-effects. There is however a lack of consensues on the temperature respons on degradation soil organic matter. This paper aim to give a better understanding on the factors controlling the temperature respons. The factors studied were the carbon substrate qualitity and the physiological status of the microorganisms.
